Peter Sauber began building race cars in 1970, establishing PP Sauber AG. His early efforts focused on sports car racing, constructing the C1 in his parents’ garage to compete in the Swiss Sports Car Championship. The team gradually progressed, competing in FIA events with the Sauber C5 at the 1977 24 Hours of Le Mans.
Sauber cars were consistently designated with a “C” followed by a number, honoring Peter Sauber’s wife, Christiane. Early sports cars like the C2 and C4 saw incremental improvements in engine power and chassis design, leading to success in domestic and continental European competitions. The C5, designed for Le Mans, showed promise but ultimately retired in both 1977 and 1978, though it did win the 1976 Interserie Championship.
The team’s most successful sports car, the Sauber C9, powered by a Mercedes-Benz engine, won consecutive World Endurance Championships in 1988 and 1989, marking a return for Mercedes to the World Sportscar Championship. Sauber pioneered several technological innovations in Formula One, including high cockpit side walls – a safety feature implemented after Karl Wendlinger’s 1994 Monaco crash – longitudinally-mounted gearboxes, and the twin keel front suspension.
Throughout its history, Sauber provided opportunities for young talent. Notable drivers who raced for the team include Heinz Harald-Frentzen, Kimi Räikkönen, Felipe Massa, and Jacques Villeneuve. Räikkönen, in particular, made a significant impression during his time with Sauber in 2001, vindicating the team’s decision to give the relatively inexperienced driver a chance. Later drivers included Nick Heidfeld, Valtteri Bottas, and Zhou Guanyu.
Sauber achieved significant success in the late 1980s and early 1990s in sports car racing, culminating in the 1989 Le Mans victory and consecutive World Endurance Championships. The team’s entry into Formula One in 1993, initially with Mercedes engines, established them as a competitive independent constructor. A period of financial instability led to BMW’s acquisition of a majority stake in 2005, rebranding the team as BMW Sauber.
The BMW Sauber F1 Team enjoyed its most successful period between 2006 and 2009, achieving its first and only Grand Prix victory at the 2008 Canadian Grand Prix with Robert Kubica, and finishing second in the 2007 World Constructors’ Championship. However, the global financial crisis forced BMW to sell the team after the 2009 season. Peter Sauber reacquired the team for a symbolic one euro, returning it to independent operation.
Financial difficulties continued to plague the team as an independent constructor, relying on customer Ferrari engines. A 2016 ownership change saw Peter Sauber sell his controlling stake to Finn Rausing. A title sponsorship agreement with Alfa Romeo in 2018 brought a period of relative stability, with the team racing as Alfa Romeo Racing and later Alfa Romeo F1 Team until 2023.
In 2024, Audi AG purchased Sauber Motorsport, intending to transform the team into the chassis constructor and sporting basis for Audi’s entry into Formula One in 2026. For the 2024 and 2025 seasons, the team competed as Stake F1 Team Kick Sauber, reflecting sponsorship agreements with gambling companies. The team finished the 2025 season with a podium finish for Nico Hulkenberg at the British Grand Prix, the first for Sauber since 2012.
Sauber’s legacy lies in its consistent ability to compete at a high level despite often facing financial challenges. The team’s commitment to innovation and its willingness to provide opportunities for young drivers helped shape the careers of several prominent Formula One drivers. The acquisition by Audi marks a new chapter for the organization, promising a return to factory-backed competition and a continuation of Sauber’s long history in motorsport. The team also established a junior driver program, the Sauber Academy, to nurture young talent.
